This invention relates to sliders for slide'fasteners of the well-known type wherein a plurality oi spaced interlocking fastener elements attached Y of a pair of opposed tapes or stringers disengaged by movement of a longitudinally of the to the edges are engaged or slider along' the elements stringere.

Such a slider consists generally of a pair of wings or plates connected to'- gether at one end by a neck or wedge portion and having inwardly extending marginal guide anges so as to provide a Y-shaped channel between the wings through which the fastener elements pass for engaging and disengaging the same. It is well known to those skilled in the art that the wings together with the opposed iianges of the slider, must be aceuratelyspaced apart in order that the f astenerv operate satisfactorily. If the wings are spaced too great a distance apart the fastener elements will nass and consequently, the slider will become displaced from the fastener elements and the fastener is thereby made inoperative. oftentimes, the slider becomes accidentally dis- -placed from the fastener elements or stringers due to many causes, for instance, material or other foreign elements may get caught between the wings and/or flanges and the fastener elements,.thereby spreading the wings sufiiciently so that the slider will become removed from the track or fastener elements. Any such occurrence is not only inconvenient and annoying, but the replacement of a conventional slider requires ex,- pert knowledge and skill.

Heretofore, various types oi removable sliders have been suggested and usedto remedy this condition, which can be readily replaced on the track or fastener elements so as to again make these sliders have hibitive. Most of these sliders employed the use of hinged plates or wings with means for locking the wings in spaced relation after the slider was assembled on the stringer. Such sliders not only of intricate parts which were dimcult and expensive to manufacture and assemble, but oftentimes, the interlocking means would wear and work loose and permit play bethat they would spread sufil-V tween the plates so ciently to become displaced from the stringers, thereby defeating the primary purpose for which such sliders were intended.

-According to my invention, there is provided a slider consisting of two independent wings or plates having interlocking 'means incorporated 2 therewith for connecting them securely together so as t0 maintain the wings atfall times, in their proper spaced relation. thereby eliminatingthe above mentioned disadvantages.

Accordingly, it is one oi' the objects of the present invention to provide an improved slider oi the type described, which is simple and inexpensive in its construction and consists of two parts which may be conveniently die-cast, ifdesired. and easily assembled.

It is another object of this invention to provide an improved slider for slide fasteners which can be readily applied to the fastener stringers at any point therealong whereby the fastener is l made quickly repairable and operative.

It is a further object of the present invention to provide a quick repair slider consisting of a minimum number of parts which can be readily applied to thefastener .stringers without the necessity of expensive tools or other equipment.

It is a more specific object of this invention to provide a slider consisting of two parts having an interlocking means incorporated therewith which automatically interlocks the two parts when they are forced together.

Various other objects and advantages of this invention will be more apparent in the course of the following specification, and will be particularly pointed out in the appended claims.

In the accompanying drawings, there are shown for the purpose of illustration, oneembodiment and several modiilcations which my invention may assume in practice.

Fig. 11 is a modified type of stud arrangement that may be used in my improved slider.

There is shown in Fig. 1 of the drawings, a conventional type slide fastener comprising a. series of spaced apart interlocking fastener elements 2 attachedv to opposed beaded edges of tapes or sti ingers 3. There is arranged on the fastener elements, a slider 4 for longitudinal movement therealong in opposite directions to open and close the fastener in a well-known manner. Such a slider consists generally of overlying spaced apart upper and lower wings and 6, respectively, having inwardly extending guide flange portions 'I along their marginal edges and connected at one end thereof by a neck 8, so as to provide a Y-shaped channel between the wings into and through which the fastener elements pass when the slider is moved therealong for engaging and disengaging the same. There is integrally arranged with the top wing of the slider, a lug 9 to which a pull member I0 is pivotally attached for manipulating the slider.

According to the present invention, as more clearly shown in Fig. 2 through 8 of the drawings, the connecting neck 8 comprises an inwardly extending substantially diamond-shaped neck portion I2 arranged integrally with and centrally of the bottom wing 6 at the upper end thereof. Centrally of the neck portion I2, there is arranged therein a polygonal-shaped hole or socket I3 which extends .substantially to a point adjacent the plane of the inner wing 6. There is arranged in the wing 6 adjacent the upper end thereof, a cylindrical hole I4 which communicates with the socket I3 in the neck portion I2. There is also arranged in the wing 6, a longitudinally extending recess or opening I5 having its longitudinal dimension extending substantially perpendicular to the axis or longitudinal dimension of the hole I4 and communicating therewith and, if desired, may be open to the upper or outer end of the wing for a purpose hereinafter to be described.

At the upper end of the opposed or top wing 5 there is arranged integral therewith and centrally thereof, a smaller inwardly extending neck portion preferably in the form of a stud-like projecting portion I6 having a polygonal-shaped cross-section conforming to the polygonal-shape of the socket I3 of the wing 6, in which it is disposed. On the extreme outer end of the studol spring that may maintain the wings 5 and nected at all times, as it is not desirable that they.

like portion I6, there is provided a reduced cylindrical stud-like portion I'I which conforms to the cylindrical opening I4 in the Wing 6 in which it is disposed. 'I'he stud I6 and socket I3 with which it cooperates, are polygonal-shaped so as to act as a key arrangement for preventing rotative movement of the two wings relative to each other.

There lis mounted in the recess I5, a yieldable or resilient member I8, preferably in the form of a spring having a. lyre or key-hole shape, as shown in Fig. 6 of the drawings. outer end of the cylindrical stud portion I'I is preferably bevelled as at I'Ia, so that it will cam the legs of the spring apart when forced therethrough. Around the periphery of the cylindrical stud-like portion I 'I there is arranged preferably a circumferential groove I9 with which the The extreme yieldable or spring member I8 cooperates to lock the wings together in a manner to be described. The resilient or yieldable member I8 is inserted in the recess I5, preferably from the upper open end of the recess at the top of the wing and is preferably permanently housed in this recess by peening or closing the open end of the recess, so as to prevent the member I6 from becoming displaced therefrom. It will be seen that both of the wing portions 5 and 6 together with the interconnecting portions I2 and I6 carried thereby, manner that they may be easily and conveniently die cast and it is preferable that these wing portions be of such die cast construction.

'I'he improved slider of my invention is assembledon the fastener elements in the following manner. The lower wing portion 6 is first positioned on the under side of the fastener with the fastener elements disposed in the Y-shaped channel between the guide flanges 1 and the neck portion I2. The top wing 5 is then positioned on the upper side of the fastener elements directly opposite the lower wing 6 with the stud-like portion I6 projecting into the socket I3 of the neck portion I2 o1' the lower wing. The two wing portions 6 are then moved toward each other and forced together with a pressing action and upon such movement of the wings, it will be seen that the polygonal-shaped stud-like portion I 6 passes into the socket I3 and that the cylindrical stud portion I'I passes into the cylindrical hole I4 in the wing 6. Upon and through the openings Il, it will be seen that portion I'I will be moved into contact with the yieldable or spring member I8, and forced therethrough until the circumferential groove I9 around the stud I1 is disposed in the recess I5 directly opposite the yieldable or resilient member I8 therein, at which time the member I8, due to the resiliency or yieldableness thereof, will fall or snap into position in the groove, thereby securely attaching the two wings together. In other words, the two slider wings 5 and 6 are forced together and the resilient locking member I8 snaps into engagement with the groove I9 in the stud-like portion I'I in a manner similar to the action of a snap fastener. It is desirable that the resilient member I5 be of such construction and possess the required characteristics to 6 permanently conbe separated once the slider is assembled in positon on the fastener elements. If desired, the stud-like portion I'I may extend all the Way through the Wing 6 with the opening for the spring being disposed on the outer side of the wing instead of in the body thereof, as shown. It will be understood that the neck portion I2 of the wing 6 is of sufficient height and arranged so as to space the wings 5 and 6 the required distance apart, that is, the outer end of the neck portion I2 abuts the inner side of the wing 5 so as to maintain the mined distance apart.

In Figs. 9 and 10 of the drawings, there are shown other types of spring members I8 that may be used in accordance with the teachings of the present invention. In Fig. 9, there is shown a rivet 22 which is split radially as at 23', through which the stud-like portion II is forced when the wings are moved together. Such a rivet would not necessarily have to have resilient characcontinued movement into wings 5 and 6 a predeterteristics and in such case. the end of the stud- 'modified construction of the cylindrical studlike portion l1 of the wing 5. In this construction, there is provided a stud-like portorrilb having a pair of circumferential grooves arranged therearound which are spaced a very slight distance apart so as to provide an outer groove 20 and an inner groove 2 l. When the two wings are forced together, as above described, it will be seen that the resilient member I8 will snap ilrst into the outer groove 20 to hold the two slider wings loosely together and in position ready to be assembled on -the vfastener elements and suiiicient-ly spaced apart so -as to permit the fastener elements to pass between the opposed flanges 1, whereby the slider can be positioned on .the fastener elements for final assembly. After the wings have been assembled onv the fastener elements as hereinbefore described, it will be understood that the twowings are'fo'rced together further so that the inner wall of the upper wing will abut the outer end of the neck portion I2 of the lower wing 6. In moving the slider wings toward each other in such a manner, it will be seen that the resilient member I8 will be moved out of engagementwith the outer circumferential groove 20 and into the inner circumferential groove 2l so as securely to attach the wings together. In 4other words, a

double snapping action results withthe outer circumferential groove 20 provided merely for the purpose of holding the complementary wings 5 and 6 together before assembly on the fastener, so as not to be displaced from each other until it is desired tc assemble permanently4 the slider on the fastener elements.

As a result of my invention, it will be seen that there is provided aslider body consisting of two simple and inexpensive parts which can be readily assembled on the fastener elements even 2. In a. slider for slide fasteners of the class described, a pair of overlying parallel wings, means connecting said wings together in spaced relaiion so as to provide a fastener element receiving channel therebetween, comprising an inwardly projecting neck portion carried by4 one-of said wings having a socket arranged therein, an inwardly projecting stud-like portion carried by the other of said wings conforming to and disposed in said socket, means engaging the outer end of -said stud-like portion for holding the same securely in said socket, and means preventing rotation of' said wings relative to each other about the axis of said stud-like portion and socket.

3. In a slider for slide fasteners of the class described, a pair of overlying parallel wings, means connecting said wings together in spaced relation so as to provide a fastener element receiving channel therebetween, comprising a male portion carried by one of said wings which is disposed in a female portion carried by the other o said Wings, and an independent member carried by said female portion engaging said male portion automatically for connecting the Wings securely together.

4. A slider for slide fasteners of the class described comprising a pair of spaced-apart parallel wings, means arranged at one end of said lwings connecting the same together so as to provide a Y-shaped channel therebetween, said connecting means including an inwardly projecting studlike portion carried by one of saidwings, the other of said wings having a socket arranged therein conforming Ito and in which .said stud-like portion is disposed, and an independent member arranged adjacent the bottom of said socket cooperating with the outer end of said stud-like portion for locking automatically the same therein whereby the wings are connected securelytogether.

5. A slider for slide fasteners of the class described comprising a pair of spaced parallel wings,

I means arranged at one end of said wings connecting the same together so as to provide a Y-shaped channel therebetween, said connecting means including an inwardly projecting stud-like portion carried by one Aof said wings, the other of said wings having a socket arranged thereinconformby the most unskilled person. In other words, it

will be seen that there is provided a slider which can be assembled on the fastener elements .by the amateur at home in case the fastener becomes damaged or the slider becomes displaced from the fastener, without the need of any tools whatsoever. n
